I treated myself to a Kreg Accu-Cut circular saw guide system for my cordless saw last year when I was building a murphy bed. (I don't normally work with a lot of sheet goods but the bed project made it a necessity; and I couldn't justify a full blown track saw set-up)

I was very happy with this piece of kit, I paired it with the FRUED 60 tooth blade below. I've since used it to cross cut some very hard wood boards since then (Maple and Chechen) and the cuts have been phenomenal.
