If you're looking for a solid Accel. that will actually come with a warranty, I'd hit up good old Amigakit for the ACA 1230/42.
I can verify that the ACAs are great cards. I have an ACA1230/28 and think it's great.
If you can grab a deal on one, all you really need is a RAM card to play WHDLOAD games. A 4M is perfect. In fact, the 8's can interfere with PCMCIA, so you might get one and toggle it to 4M anyway.
I used an 8M (usually with only 4M enabled) for a bit and it was great for WHDLOAD.
Only issue is that sometimes, these sell for almost as much as a 030 accelerator.... But if you get a good deal, I wouldn't be worried if your goal is WHDLOAD.
