Blizzard 1230/50 advice needed

[AEV]

Hi I was wondering if some of you knowledgeable guys could help me. I'm looking to buy an accelerator for my Amiga 1200 specifically a Blizzard 1230/50. The thing is I have the option of either buying the following:

Blizzard 1230/50 MK I 030 @ 50mhz
or
Blizzard 1230/50 MK III 030 @ 50mhz
or
Blizaard 1230/50 MK IV 030 @ 50mhz

I know that the MK I can only have a max of 64MB of RAM versus 128MB for the MK III and IV.

So apart from the RAM difference could somebody give me some advice on if the MKIII or MKIV are the better choice. If anybody could tell me their experiences and any problems with these cards that would be great too.

Thank you for reading
;)

I have a 1230-IV here. It has just one big problem, it doesn't work with some ram modules and there's no way to know if a ram will work or not unless you try it. Apart from that, it's a very good accelerator and there's no indication that older 1230s don't have similar problems.
