Best 320x240 Camera Hardware/Software for around $500 USD

Firstly I HATE this sort of thread as it promotes mine is better than yours or 'I heard once of site X online Brand X is ....' instead of actual factual information.

I am not interested in tinkering or having to mod/rebuild or program a better mousetrap (that may change of course  ), so what is the best readily available commercial solution to this sort of spec. In this day and age most of us have a tablet or smart phone so having a screen on the camera or not is unimportant and better spec is more important.

320x240 Camera or a bit more to the TE-Q1
Temperature Range -10 or more to 300C
9 FPS is fine and keeps any potential  import issues minimal
Ability to be remote mounted from the attached device if possible.

Options?
TE-Q1 Pro
SEEK Compact Pro
Xtherm T3 Pro
HT-19 (bit more than the budget?)
Dianyang 320x240 which will run on the SEEK software. Guinea Pig option but I am tempted to take the plunge @ $399
Other better Apps or Software that will work with any of the above?

any others I should be considering?

The TE-Q1 non-Pro can also do higher than their specified temperature "limits". A quick check with their android app default setup using my TE-Q1 with 13mm lens measured a stove going up to around 240C (value changed only slightly depending on the camera orientation/direction). Whether that was the limit of the stove (i do not think this was the case) or the camera and how accurate that high temperature value is, or e.g. whether the camera has been calibrated for the 13mm/1 lens or 6.8mm/1.3 lens, are something I don't know. (The SDK's internal temperature tables go from -30 to 260, but I think those values are missing +20 of ambient correction or something.) I've read in older thread of TE-Q1 showing values up to around 280C, but I've not read anywhere that this model would have reached 300C, so might still not qualify.

The Xinfrared dongles do compare to the ThermExpert rather well. There is a side by side post and some said that it won. Worth considering. ThermApp might be an option as you can likely get it used for your budget.

Thanks, I really need to be around the 300C. Coffee Roasters I play with run at Air Temps of 230+ and the metal above that in places. General Commercial Ovens will be up there too and I do play with them from time to time.

Thanks I will add any reasonable options to the first thread if any others want to follow later
