I decided I would pass on the new Gym Challenge promos. I ran into some unexpected expenses and decided to put my promos on hold. I'd still be interested in the LL set a little bit down the road (but again, depends on what you want to do with it).
NarcoticHobo, That sounds reasonable to ask $1K for just the base sets and no SR/UR. I understand you want to sell the HGSS cards altogether, but would you perhaps consider a trade on it? I have a handful of extra promos and that Neo 3 partial set. If not (and you'd rather sell in a lot), that's fine too. Figured I would mention it.
NarcoticHobo, I considered selling off my BW sets as well and came to the same price. Should include everything from BW1 to EBB in 1st ED (although I didn't have a single deck when I considered selling my sets, so that makes your offer a better one). It is difficult to find a buyer who will drop $3K on an entire era, so I would consider accepting offers as low as $2.5K if the sale is a private one (without fees).
I am actually still very interested in the HGSS cards! I recall that you don't have any RH left, but do you still have the Lost Link set? I missed an auction for one awhile back and could use it.
NarcoticHobo, That is kind of expensive but not a bad idea. I don't think they will drop in value anytime soon. I made some purchases to finish up the Neo 3 set and it is currently missing 3 cards: Ho-Oh and the two Shinings. I would think it is worth around $100 but I might be wrong on that.. Sets on eBay are all over the place and vary in condition and completeness.
