I've never ordered from Lesley's Patterns so I have no knowledge of the business. I've ordered my blades from artcraftersonline.com and have been completely satisfied with their service. The proprietor, Denny, is on several of the scroll saw forums and is more than helpful. He sales Pegas blades and almost always has a special to receive 10 to 15 percent off your order with the appropriate code. You can go to his website and indicate you would like to receive his monthly newsletter which always has the appropriate sales code for that month.
Also, Bear Woods is one of Steve's sponsors and they sell several brands of blades. I've never ordered from them but I can almost assure you if Steve is associated with them their service is good.
