This reponse is probably too late for davlaf, but maybe for future reference =)
Another alternative to biscuits is pocket holes (Kreg is one brand name). Jigs aren't too expensive, pocket holes are easy to do, and they have the added advantage of a mechanical fastener (the screw) in addition to the glued joint. The screw also acts to clamp the joint together, so you'll likely need fewer clamps to ensure the joint doesn't separate before the glue dries.
