Don't feel bad I started last month and have about 190 names. I have spent more and also made several rookie mistakes along the way. I bought some in auctions, got some on the drop, and others I have hand registered. I have not put very many up for sell as most I have not had past the 60 day registrar lock. So if I understand it correctly I can't transfer them anyway.
I have played around with Parking them at both Godaddy and Bodis. I don't see this as being very profitable and will probably eventually go to custom landing sale pages.
I am only actively domaining for about 6 months although I have had my own domains and websites for about 5 years. There is just so much to learn and there appears to a lot of confusing information for a beginner. In life as with most things I think that I tend to keep things simple. I tend to gravitate towards the market leaders as my view is that they got to number one in their field for a reason.
Therefore, I think that when I list my domains it will be with GD in an auction with a BIN figure. I am still learning so when I am leaner and richer I can review my strategy.
The one thing that amazes me after countless hours researching is that I don't feel that I have done too badly when I see some of the domain names that people with much more experience have for sale. I.e. any two random words put together that make absolutely no sense in the real world or the domaining world.
I guess that anyone can buy a domain but the real difference between poor and not so poor is the art of marketing and selling a domain. Perhaps I will just use the K.I.S.S. approach.
I mean, how hard can it really be...right!!! LOL
