I already blogged about the Game Gear I ordered on eBay for 25€ boxed, however the situation has change quite a lot since my last blog entry. 
First of all the Game Gear was delivered to my house, but when I put in the six double As it requires all I got was 1-2 seconds of life out of the device. "Bad sign" I thought, essentially because it said on the auction page that this thing should run like it's new... So I emailed the dude who sold me the Game Gear and demanded compensation for the wrong description. Meanwhile I bought a second defective Game Gear (this time I knew it didn't work) for 1,50€ on eBay to get some spare parts for the other one (The display has horizontal lines failing) and some capacitors to fix the regular sound and display failures (tutorial on youtube). After that I got word from my first Game Gear seller that he still has Sonic 2, Prince of Persia, the TV adapter, the AC adapter and another faulty Game Gear lying around and his willing to send me the stuff to keep me happy - deal! 
In addition I bought a couple of games, some of which where recommended by you guys: Shinobi, Sonic 2 (damn), Sonic Chaos, Aladdin and AX Battler 
I also ordered Panzer Dragoon Orta (XBOX), Panzer Dragoon II: Zwei (SAT), Battle Engine Aquila (XBOX), Gun Valkyrie   (XBOX) and Jade Empire (XBOX) 
So I am really looking forward to get my hands on all the stuff I ordered and of cause to playing on a working Game Gear. I'll keep informed about my progress with the repairs, the components should arrive within the next week.  
So long then!
