Behringer BTR2000 Vs Polytune

Hi there guys, just hoping you could weigh in and help me out with choosing a rack tuner. Basically at the moment I'm using a floor pedal Polytune for all my tuning.... Tuny... Ness and I was hoping to move over to a rack mount tuner, with the obvious barrier being that this **** is damn expensive. That is except for the BTR2000 which at a glance seems to have all the features I need in a tuner, so my question was: Aside from the multiple-string tuning feature which I never use how does the Behringer compare to the Polytune? I know it gets a lot of hate but for all I know that could only be in comparison to other rack tuners, as long as it's not a downgrade I'll gladly swap over my Polytune for it as I'm getting tired of the time it takes to set up a amp and pedalboards seperately at shows when I could compress all my gear into a single rack.

 

I don't use a 5-string but I do often play drop tuning with my E string tuned all the way down to C. That being said though I'm very intent on swapping all my gear over to rackmount gear so I can cut my setup time for gigs. Are there any equally cheap rackmounts out there that work?
