Graz if you were considering the axminster c4 then the chester comet is 183 quid cheaper
I have had no problems (touch wood) with my c4/comet but I have never been 100 percent happy with my compound and must get round to making a new gib for it

The DB10 has a bigger chuck and through headstock which will come in handy and a threading dial plus the extras you mentioned but from the picture it looks like it does not have a cam lock tailstock
Unfortunately it does not look like chester have stock of either model
There must be members on here with experience of the DB10 who could point out it's pros and cons ?
