Our shop uses precision blades, they seem to be pretty reasonable priced, I believe they are approximately $3-$7 wholesale. You can stock pretty much everything you need for $300-$400. We mostly use the 17"-19" range so of course buy more of those unless you might be doing a lot of big trucks or such.

They also offer some winter blades, but I didn't order them last time, so I'm not sure what the prices are on those.

Our shop also offers an aquapel treatment which we do well with. We offer a package of $39.95 for new blades and new aqua (which you can do repeat sales in 6 months - it's lifetime), but we usually sell it for even less than that because the cost is nominal... and we tell them we have it on sale. It works well, you can easily add $25 onto an order thats only going to take an additional 15 min. $100/hr is good money.
