Thanks @farkas! The FX Aid XL was a top contender. I almost got it instead of an MFX. Unfortunately it now looks like it is also sold out everywhere. A place I usually buy from had it a week or two ago :(

I found one retailer in England selling it but it looks like they won't ship to me in the US. Sigh... the module availability situation is getting extremely frustrating. I'll keep looking. Or maybe I'll go with one of the other options, or reconsider if I even need multi effects right now.
