I know I'm repeating myself because I said the same in 2 other threads today (seems like today is the A1200 turbo boards day or something), but the best boards and the only ones I would recommend without a doubt are blizzard boards by phase5..
So if you don't want to spend too much money, you should get a blizzard 1230-IV (older versions are also good, I use a 1230-II and never had any problems).. and if you want a really fast system you should get a blizzard1260.. I had both a 1230-IV and a 1260 and NEVER had any problems with it..
also, if you buy a blizzard 1230-IV with scsi kit and you decide to upgrade to a 1260 one day, you can keep the scsi kit because its the same for both cards.. its up to you how much performance you need and how much money you are willing to spend.. for a comparison of 68k cpu speeds go to
amigaspeed.. you will notice that a 060 can be more than 5x the speed of a 030 at the same clockspeed..
