@adonay: er, well, on the eBay I had to pay £70 (i think it was) for my Blizz 1220/8mb about 5 weeks ago. That's almost the average price a Blizzard 1230 was going for this time last year. Last time I looked (again, about 5 weeks back) 1230s were going for £150-£170. I actually sold my 030 for £170. God only knows how much 060s are selling for now.
But yeah, having had the entire range of accelerators, I would recommend a 030 - all considered. Especially since you will have the Sam to cover higher Amiga performance requirements.
Unless, of course, you are into modern Amiga demoscene productions. In which case, a 060 is almost essential.
