If you want a router buy a router, likewise, if you want a laser then buy a laser. Mixing machines never work out well. Also, your budget isn't going to get you anything that's any good in either format.

My advise is look for a second hand machine that is well built because with £1500 your not going to buy anything new that is anygood. You'll need to double that budget if you want a decent router, laser I'm not sure about as it's not my thing but I think any decent laser will be in the 3K bracket.
