Well I caved, I may have ended up wasting money but I just bought the SL's for 270. Granted they are probably gonna be cheaper in a month but I was only able to find one store that had the M/L's in stock and figured I would have a hard time finding them in another month or so.
Many thanks to everyone who helped me I really appreciate all of your advice. I think I am gonna be pretty happy when these babies arrive!!
