Should I buy the "professional" TBS6983 or TBS6902? Big difference in price and capabilities. But can I take advantage of the enhanced capabilities of the TBS6983? I'm not sure if I should buy the more expensive model. I'm looking to get something that does 16apsk. The lack of linux based blindscan software concerns me but I don't see anything else out there that would convince me to buy some other brand. I may have to brush up on my C programming and try to build my own linux based blindscan software - programming is very time consuming so I'm reluctant to do it so I guess I'll just have to live with whatever is provided by the vendor.
