Best option is a TCON-17 via the numbers of reviews I read, and well I had it hands-on myself too. So yea, it did the job, although you can still expect contrast loss. The image was still fairly sharp.
I haven't seen it selling in shops, I heard that it goes for 135 brand new at TK (bugis). Should be only around 70-90 2nd hand.

Anyway guys, I found this website that sells stuff pretty cheap and they deliver worldwide for free. I'll be buying some items from there, just wondering if you guys want to hitch a ride and we can get the bulk discounts, they have photography accessories there.

I've looked through some of their products, mostly are 3rd party stuff, although they seem to have some genuine stuff. Avoid the filters unless its something you don't use often (like a star filter). Avoid the memory cards too, they look iffy. Generally, only buy things that are dirt cheap and that you generally can't go wrong about. (Hoods, Straps, Covers, lens caps, Blowers).
They're known to be reliable but somewhat slow (like 1 month delivery), or so I gather from other photography forums.
So let me know if you guys wanna get some stuff, I'm only opening it to my friends on this thread, so yea =), try to keep it to the low cost items only, and I'll actually require you to transfer me the money first. (Don't worry I'll try to print the invoices to prove that I'm not taking a slice out of it!)
I'm already getting 2 items, their discounts are for 3, 5 or 10 items together. =)
