A buddy of mine bought an enclosure exactly like that (if those are 10s) at a yard sale once.
He gave $20 for it. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif
Was it worth $20?
Yeah. They played.
Would I pay $50 for that?
No.
Once you decide to upgrade from that (and trust me, you will eventually...) you'll never recover even half of your investment.
Twistid's idea has merit ~ $30 would be reasonable but no way would I pay more than that for those. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif
