I have the same problem with my hands and flat bars - I've done two bike conversions to drops & bar end shifters - both bikes are triples and without changing the FD - you will only be able to use only two rings. The only thing you are missing from your costs is some type of bar tape. From the learning standpoint - if you look at the you-tube videos and take your time - you could do it your self but you will need a good cable housing cutter or dremel tool. It also gave me a reason to get a bike repair stand which made the job so much easier. Would I do it again - yes, but the cost was not an issue.
