1.) Where should I buy it?
So far I've seen Chinavision (????) and ThinkGeek (dealt with them before). I'm seeing roughly a $20 difference between the msrp on both sites. ThinkGeek has a current free shipping deal for orders $75 or more using the promo code "shiny".
Id recomend HKstore (

2.) Are there any newer models being released I should wait to buy instead?
there are no models planned (or at least that we know of) to replace the A320. even if there were, these sorts of devices come about all the time, and rarely do they perform as well as the dingoo. id get an a320 if i were you, since its pretty awesome for the cost.
3.) In regards to firmware flashing, anything I should note or be careful with? I've flashed Sony PSP units and I'm pretty tech savvy.
nope, its pretty straightforward, plenty of threads regarding it. if youve flashed a PSP before you should have no problem.
4.) Anything in general I should know about?
just dont expect perfect performance, alot of people seem dissapointed with the dingoo. in reality its one of the best devices of its kind, especially for its price. it performs well, but until the community really begins to explore what its capable of, we wont have perfect software.
Mu major concern on this is the screen. I own a OneStation handheld and the screen itself is great, but the build around the screen is poor. I have since gotten dust inbetween the case lid and the lcd board below, which is very distracting. I don't plan on taking this with me many places, its not going to be in my pocket, probably wrapped up in a desk drawer when I'm not playing it.
the screen is completely filled over, so no gaps to collect dust, and it even has a brilliant screen protector over the top. the build quality in general of the dingoo is awesome.
all in all, its a great device and i have no reason at all not to recomend it to anyone.
