love my '04 883 custom. wanted the 1200 custom but this one came up and I went for it. I do not regret it. I think the parts will be available so go for it.
I love the Customs mainly because the C should stand for Chrome. It has it's own distintive look and I hope Harley doesn't get rid of it and replace it with another dark bike.
I love my custom. If I were to do it again I probley not do it again. I added +2" forward controls, put longer rear shocks, changed the seat and removed the stock riser. I installed a Nightster riser for my apes. The only thing that is still stock on mine that makes it look like a custom is the fuel tank and headlight. I should have bought a regular sporty and added my mods but if you like the sporty as is I think its worth getting.
