Don't bother with the Chester imo.
1. The Y travel is way short at 155mm.
2. The taper MT2, no thanks!

A better variant is the AMAT25LV from Amadeal. R8 taper avail which is best imo. Has more powerful motor, belt driven, higher rpm. If you're going to spend around £1200 then for me that's the one to get (and I am).

There's no guarantees the G0704 kit will fit any of the variant mills I'm afraid but the one I've mentioned has the best chance.
