I know what you mean...I have been a CD collector right from the beginning. I have at last count 6700 cds. When I bought my first home I had to make sure there was a room big enough where I could build my shelving unit. I now have what resembles a library and am getting close to running out of room again. Maybe I should have invested in mini discs.
Still on my want list:

Nick Gilder- 'Nick Gilder' (1985 RCA) extremely rare!!
Tim Feehan- 'Tim Feehan' (1987 CBS) includes 'Where's The Fire"
I wouldn't mind finding 'The Wraith' soundtrack on CD. It has two songs from these two CDs on it.
Anyone looking for any rare AOR Melodicrock CDs...I may be able to help you out. Except I'm not into many 80's hair bands....
