I'm currently using the Rolad TD-11K and the sound is great. I've been using it for 3 years now at matibay sya considering na heavy hitter ako. Magagamit mo din yung pedal mo even if its a double pedal. So, in short, I suggest that. Hope that helped in any way.
Another thing, if you own a credit card, wait for the Sale and use your card to get the installment option para di mabigat sa bulsa.
