The castle creations MERV fell through he didn't accept the 300, I didn't bother making a counter offer...it'll be more enjoyable to do the mods myself instead of cheating the experience.
On another local site (infomall), I found a MERV for 100 even I'm just not sure what's powering it from the pic it looks like the same set up as mine, although its really hard to tell the pic is dark and grainy, and it has one of those heat sinks with the fan. Waiting on a return email, and its in driving distance, about 30mins from my house.
Also grabbed what I think is a XXL for $75, from the same site, it was 10 mins from my local grocery store so I said what the hell! why not. It kinda looks dirty and worked over but with a lil attention I think it can be a runner.
