Please help me find my wishlist items

I only have two cels, because I've only just started my collection. I was in the chat room and they suggested I try asking on the boards for help with what I'm looking for. Right off the bat I can tell you my highest priority cels are Phibrizzo (Slayers) (I really would give a kidney practically), any really good cels of Priss (Bubblegum Crisis) (especially in her stage costume), a cel of either Angel or Omar from the hardly-known Canadian movie Rock and Rule, and a really nice, detailed cel of Ayeka from Tenchi (preferably the OVA). I have looked everywhere, including animanga, anime gambit, animegame, ebay, anime-cel, asylum anime, and even galleries on here. If anyone can help or even wants to make a sale (email, of course, since we can't on here) I would be forever grateful.
Thank you so much for reading and helping a cel newbie out!
If anyone wants a direct link to my wishlist, it's http://sletia.rubberslug.com/gallery/wishlist.asp If anything, I can promise really nice screencaps. ^^;

Some of that stuff can be found on ebay if you're really diligent and look about every other day. Also, make an acount with a deputy service so that you can bid on YahooJapan auctions. You should also make an acount on the anime-beta forum and watch the cels for sale board.
Sorry, I know this advice is really general but, that's because I don't know a lot about the series you collect from.

Good luck!

I know where you can find that particular Valgaav cel..
I have one from the sequence and I love it !!
Another one can be found here:

Although, I paid less than that for mine ^^;
