I got to step in to defend Carlos drumsets. As we are talking about value for money here, quality wise we can't really talk much at this price range.
I believe the comparision is between the sets in the price of S$499 or so kind of drumsets.
For this price, you are gettin on a carlos set: Bass drum, 2 toms, 1 snare, 1 floor tom, 1 hi hat stand, 1 straight stand, 1 boom stand, 1 snare stand, 1 drum trone, (chair), 1 drum pedal, 12" 14" 18" (4pcs cymbals), 1 pair sticks. (incl delivery)
For the same price on others, you will not have the boom stand and extra 18" crash ride cymbal, you may not have the trone or any cymbals too.
Yes, I agree the shell on the carlos somewhat rough in texture, and the plastic laminate not glued fully. But properly installed, the set still delivers to standard. I am saying this as I am using it for my jamming studio for more than a year, still on stock skins (protected). My customers seldom complain.
The most important thing I feel, is to buy with the set delivered and properly installed by an experienced person (sorry you have to pay them for this what). DIY will not be advisable,
For the money, I think Carlos is the best choice. But now still out of stock from the distributor. (They do have a slightly better model at about $100 more).
