[Discuss] any good alternatives to ebay?

[MC]

time to buy another iphone...used of course, cause i don't shell out for 
new. Ebay is OK, but nothing is listed that i need or want. since 3g is 
getting booted, i'm looking for a 4g lte that isn't antique enough to be 
booted soon. so...any suggestions? Anything comparable to EBAY? maybe 
someplace that might have more tech oriented stuff to auction? Got a 
headache and gotta sign off. MCB

PS: used a BBz10 for all these years until they were shut off. Im 
thinking about a BBz30 because how can I go wrong with $75.00 plus 
shipping? Comments anyone?  MCB
