It would be ok for cutting most PCBs, but I wouldn't do much more than that with it. I've already posted my thoughts on that machine here, so I wont repeat it.

Good to know but I suspect that I am operating in a completely different level to you Jonathan.
As a complete novice, I think the CNCDudez desktop machine will more than adequate :)
If it is as good as or better than a YooCNC 3040, then I will be very happy.
One of the last things I learned about procuring CNC machines (I'm slow on the uptake) is to build/buy it to the spec of the main intended purpose. Just about all people asking about buying a CNCs machine say...I'd like to mill a bit of acrylic, but maybe aluminium too. Or I'd like mill pcbs & the odd bit of mild steel(!), etc.
IMHO, you'll get the best results (satisfaction) by buying for the main intended purpose - extreme example to underline the point - you wouldn't buy the missus a juggernaut to go to Tescos etc.
I'd say if you want to mill pcbs, then IMHO you want a *fast* & quite compact machine (less vibrations) ...by fast I mean zippy rapids, (else it gets dreary waiting yonks for all the tracks to mill), but by bulking it up to say, start thinking about milling Ali, then you lose the attributes that your machine needs for the intended purpose.

The "CNCDudez New 2012 Desktop Mini Muscle" (catchy name) is a small machine - the working area is only 310mm, 310mm, 90mm
HankMcSpank: What would you recommend for milling PCBs?
No larger than 30cm in either X or Y plane (to keep associated frame/table vibrations lower)
Ballscrews - absolutely essential
Homing switches - virtually essential.
I could only find one manufacturer where I could buy to the above spec new (vs building my own)...
2013 new design desktop cnc router machine RS-3020 for aluminum, View desktop cnc router machine, Redsail Product Details from Jinan Redsail Tech Co., Ltd. on Alibaba.com (it costs about $1200 ...which is great value, but of course there'd be shipping & taxes on that)
(nb: my machine above is presently showing a standard 300W air cooled spindle, pending fitting a water cooled spindle over the coming days - hence all the black cables & tubing dangling in mid air near the spindle!!)
...it's the machine I ended up buying (& believe me...I went to the far end of a fart sourcing a machine that will mill pcbs well).
Sure, it's a Chinese machine but far superior to the standard Chinese CNC fayre ....it uses 3 individual decent stepper drivers (e.g. instead of a YooCnC '3 in 1' nasty driver pcb).... http://www.moonsindustries.com/Produ...t_E/SR4_drive/ The gantry uprights are 15mm thick aluminium (very solid), ballscrews...the machine is very very zippy. The machine comes fitted with homing switches (which most don't - ok, not a show stopper, but nicer to have them fitted at the factory)...water cooled spindle etc. it also has one of those cable tidy thingymajigs fitted to allow the cabling to move with the axises neatly)
You can maybe source in the UK from Redsail Cutting Plotter,Laser Cutting Machine,Laser Engraving Machine ...but I don't think they have that particular machine listed (& therefore presumably not in stock)
If your intended purpose is to mill pcbs, then I'd also say to buy CNC-USB vs. mach3 ...as the former has specific integrated features that make milling pcbs much less painful (auto Z levelling, camera point transformations to assist with double sided pcb registration etc)
