Don't feel bad sgopalam it's a common addiction. I panned ShoppingOn.com but I have plenty of worthless names in my own portfolio. A lot of times I woudl see one that I knew was only so-so, but thought well it's only $8. But after doing that a few dozen times it adds up to real money!! I now try to reg only names I want to develop myself unless I am pretty sure they have some re-sale value (unfortunately those are few and far between).
I must say I have learned a great deal from the experienced hands in this forum and I think I almost have myself under control now!
