Ways of adding Fast RAM to my A600?

[taemiga]

OK, so I've been browsing Vesalia.de and AmigaKit and all I can find in A600 ram expansions are the A602 and A603, which are both Chip RAM expansions.

I really want Fast RAM, though, 1MB chip is enough for me. Problem is, I haven't seen any Fast RAM thingies for the 600. Where are they?

I know I can use a PCMCIA SRAM card, but that's not really an option because:
1. I already use a PCMCIA SD card adapter and want to continue using it.
2. SRAM cards are hard to find and way too expensive when they do show up.
3. I heard that PCMCIA-based RAM really isn't so fast and actually can slow the whole system further down (not sure how true this is, though).

Are there "proper" RAM expansions like the A602/A603, and if not, could either of these two somehow be altered to become Fast RAM instead of Chip RAM? Even 1MB would do it for me, though 2MB would be really great.
Note that I don't want to end up with Slow RAM either, i.e. RAM seen by the system as "fast RAM" but really running at chip-RAM speeds.

Ty in advance.

OMG, yes, I completely forgot about the A608. Hmm, but I don't have that kind of patience, or even the need for 8MB...

I might just stick with an A603 anyway and just get 2MB, and not worry about it being all Chip RAM. Matter of fact, what's the speed difference between chip and fast on an A600 anyway? Probably not that much that I should really need to worry about it. I know the little bugger is just slow by design, anyway.

I prefer a real HD over an IDE-to-CF adapter btw, and I can already exchange files between the 600 and my PC either by plugging the HD into my laptop and accessing it via WinUAE, or simply with the SD card I use with my PCMCIA card reader. (I incidentally picked up that card reader in the erroneous assumption I could use it as PCMCIA fast RAM, now I know only SRAM cards work in that capacity - sorry for the pun) :-P

In the end, the A600 really is only meant for transferring all my stuff to my WinUAE environment anyway, where I can pig out to my heart's content in terms of emulating a super-Amiga.
