Carbon Computing (772 Queen St. East) is always a good bet. The most reliable SSD is probably OWC's
. I recently bought a Mushkin from NCIX and that seems to be fine; Mushkin seems to lean towards the Mac community with their products. If you check NCIX's sale section, they have a Mushkin 240GB for $169 and a 120GB for $87. I believe there are kits available that would allow you to do (3). If there are, OWC would have them for sure.
