WTF is right....
I mean if you thought you were buying a chip & having him install it... than you were pretty close to retail & a bump on his side from my point.
You can get a great chip on the market for around $35 to 40 USD (if you just buy 1)
If you order in bulk which is what most modder'd do.... you can grab a bunddle of cheaper one's... that have to be soldered in for around a bulk rate of $5-10 USD p/chip.
My prices & others in my area: Dallas,TX
TSOP Flash $20 w/out switch $25 w/ switch
Modchip $15 for v1.0-v1.5 $20 for v1.6 and v1.6b (plus chip cost)
HD Upgrade $10
Controller ports LEDs $25 for all four
Controller buttons OR jewel LEDs $15, buttons and jewel for $20 per conrtoller
Xbox Jewel LEDs $25
Some of the replies in here are right on... I do feel that the cheapest way to go to get the most out is TSOP. Myself I have one with a chip & 2 w/TSOP flashes. All work the same & in the end get what you want done. Total noob's in this area get ripped all the time. The common misconception is that you need a chip. I agree a TSOP is a rip off (to chip companies), but what are we all doing when we install the chips... I mean come on the whole thing is a way to rip off and/or mod your xbox beyond it's intended purpose.

End result... you jumped out there before knowing all your options & the games that modders prey on noob's. So you got burned, but your xbox is doing or is able to do, what I am sure you need it to. If your wanting a diff. dashboard or bios to accomadate a bigger HDD... then re-solder the points, read some posts & play with it... That's just my opinion!
BTW: I know this started as a post to find out what happened, but has really turned in to a bitch fest. If I were you... I'd run up on him & beat him like he stole something... LOL
