Personally, I would say just spend the cash and buy three LME49990 (6 chips) pre-soldered adapters, cost around $60 (Frugalphile, on eBay).
Those op-amps are very tiny.
I bought 10 LME49990 chips and the adapters and solder and the solding iron.
When I finally open the box with the bare op-amps, and saw how small the op-amps are, I knew I was in for problems.
(Me having 48 year old eyes, is also part of the problem with soldering little op-amps)
I wish I had just bought the pre-soldered, before wasting my cash on "parts".
I ended up buying pre-soldered AD797BRs from China.
Like I said eBay isn't an option really. I only need the opamps for the I/V (I only use the HP amp, so the buffer isn't used).
I'm leaning towards 2xTHS4032 and making my own adapters (which isn't an option with the LME49990), soldering isn't a problem since I soldered tons of SMD chips before.
Looking on Farnell I see two versions of THS4032:
CD is cheaper for 2€ but I can't find any difference in the specification PDF...what's the difference.
