DLA's

[Hammerhead]

Hey guys,
My Inline 5 DLA allows me to connect to the ABS Controller in my truck and the Bendix ACom software is free.
BUT I cannot connect to the Cab Controller in my KW with an Inline 5.

I know I have read on here to avoid the Chinese Nexiq adaptors as they are known to be flaky when working with the stuff we like to play with on here.
I have seen JPRO as well on eBay, but they are quite pricey with their subscriptions as well.

So here is where I'm looking for input;
1)Which DLA would you use?
2)Where would I look for one & price?
3)What am I looking to avoid?

Pros, cons, knocks, loves, and what is it I don't know about that I'm not asking?
