Xenon is pretty chill. since it can take both KV types..

and is generally cheaper than other motherboards due to xenon being an older model of the xbox

Falcon Or Xexon

--- you could Find them for about 150$-200$ (banned & Console only)

--- Or you could Find them for about 225$-300$ (unbanned & All Cable's)

Buy From....

-Buy from someone on Ttg That 110% Trusted.
-Ebay

I would say buy from one of them : )
Goodluck

Xenons are usually the cheapest but they do get red rings the most.

To get an idea on prices just go to the marketplace forum and there are a bunch of shops

If you get xenon make sure you get 12v fan mod.

Xenon:

Advantages: Takes Both Type's of KV's And The Cheapest

Disadvantages: RROD's The Easiest And Non HDMI


Falcon:

Advantages: Takes Type 2 KV's and is the middle so its mid ranged priced plus because its before jasper it is kinda of immune to RROD

Disadvantages: still a tiny chance of getting RROD but you can avoid it with Whisper Fan or 12V fan mod

Jasper:

Advantages: The Ultimate Bad Ass Console even a Jasper Arcade is worth more than a xenon with 20GB Hard Drive lol Built in memory so you have bigger nand which people refer to as Big Block (512MB on Board) or Small Block (256MB on Board) memory immune to RROD !!!

Disadvantages: getting very rare to get a jasper arcade or elite since they came out the latest and if they are jtagged pretty expensive
