I now have the TD6-KV for two months (September) and I'm really happy!
First, studying and being apart, I wanted above all a way to play the drums, but without disturbing the neighbors. It turns out that the TD6 is really affordable, and meets still to minimum requirements! I will mention to the snare mesh: it's really what motivated my purchase!
Aquérir before I could try it one time in the store (it's still the advantage of the shops over the internet!) And I went through many forums. But apart from TD3, I could not try other models. the demo site I enjoyed a lot too: https://www.rolandce.com/productinfo/productinfodetail-F.asp?Welke=426
The value is there! The Roland is solid (not like I'm playing a beef, but I do not measure my shots) and sound are truly stunning (especially the hi-hat, and snare drums).
The only downside is the bass drum that my downstairs neighbor gene, and the rubber pads are a bit noisy (tom), hence the use of a headphone insulation to prevent sound charley 'poc' quest ".
Plus I play more I'm having this drumkit! The customization is complete, it can also evolve (addition of a pad or cymbal) easily.
