Have you checked out PhotoVision ? They have GREAT seminars. A lot for your money!
I have subscribed the past 2-3 years. I love the DVD sets I get from them and I learn so much.
Normally they cost $149 but you can get a discount right now if you use my discount code, PVFAN, get it for only $39 ... It's totally worth it. You could attend one seminar for this price, but you get a year's worth for just $39 and they are great seminars!
