Help Timothy get a new drum set

My current drum set is dying. My Drum set is about 4 years ++ old already. I bought my current drum set second hand and it was good enough for practicing, but with the cymbals becoming wonky, hitting it sometimes gives wrong sounds (e.g hitting a bell gives a crash sound). Also one of my smaller cymbals has already died and I have another cymbal becoming insensitive and only giving off very soft sounds. The sound module (the brain of the kit) is also very old and doesn't have the updated, clearer sounds.

With the new kit, I will be able to improve the quality and effectiveness of my practicing as I will be less frustrated about the odd sounds and the never ending influx of problems that keep occurring when I practice. Basically, the new kit will reduce the amount of time spent fixing the kit than practicing.

Also, a new kit will probably last me another 4 years :)

With S$4000, I will be able to buy: Yamaha DTX720K and a Drum carpet to put underneath

P.S the currency is in SGD not USD!!!!!
