Never used DMM but I've heard good and bad things so who knows, you just have to try then make up your own mind.!

Ask fred about C5 because I've had C5 from him before and I think he even has or can get Ground screws in shorter lengths. Unless they have stopped supplying them.?

You have to stop at some point because you can go on for ever choosing better quality or performance parts, each upgrade usually affects some other area which then needs upgrading to match else it's pointless. The better machine isn't the one with a few high spec parts, the one that uses lower spec parts that are evenly matched will be the more balanced machine and overall usually work best. . . . Remember machine is only as good as it's weakest link, upgrade one area the rest becomes weak.!!

Can you specify some of the bad things? But, yes I will most lilely go for these anyway. Many have used them with great success. The manual and software is really good (not chinglish!) There must be bad things about the Delta servos also.

Fred can supply C5 ballscrews but it will be TBI brand and expensive (about 2.5x more expensive)!

This I have noticed, haha. I have saved every iteration of the machine design. I am up to v11 now..

It's been a while but it mostly related to the encoder's output from the drives when using with a controller that can fully close the loop. There were some timing issues that caused problems between controller and drive. But that was some time ago so they will have probably resolved that issue by now but I've seen all kinds of little things and conflicts on various forums etc.
But like you say Delta and other manufacturers do have there own issues as well and it's how they are resolved that matters most, DMM are very good in this respect I believe,
