Mscat,
I wanted to add that you don't need to buy all your grooming supplies at the same time. I first bought the Wahl peanut clippers ($40-$50 at Sally's Beauty Supply). I already had nail clippers, and combs and brushes and some hair cutting scissors. I just use my own blow dryer set on medium to dry my dog after his bath. I am still using the shampoo and conditioner I bought a year ago. I use my own Matrix Instacure as a detangler. I bought a nice "lot" of used grooming tools on eBay for $15 which included scissors, two thinning shears, two combs, a brush, nail file, a mat comb, shedding tool, and a couple more items. I had a cute toolbox already that I've always used to keep all my grooming tools in. I have tools that date back to when I raised Afghan hounds and cocker spaniels.
I highly recommend Petedge dot com for your grooming supplies. They are reasonably priced and if you sign up on their email list, they will send you updates with their sales. Email them for a catalog. They have almost everything you can think of for dog grooming, and most groomers buy from them. Use that money you would spend on grooming and buy yourself some quality tools. I think you'll recoup your investment in just a few months and you'll be so pleased with how good your dogs look when you groom them to suit yourself.
