Two bikes now, about $1000 each originally.
That was more than I thought I'd spend, but they are a recumbent and a semi-recumbent--and at the time there were no cheaper alternatives.

The totals now is about $1800 and $2300. That's all the accessories and parts replacements/upgrades.

There are other bikes I'd love to have for free, but none I'm planning on buying unless something catastrophic happens to one of the two I've got.

Two accessories I don't have yet are touring bags and some kind of a trailer for hauling cargo, but I have no pressing need for either right away.

The "cost per mile" is worth bringing up also; I expect these two are all I'll have for a while. If I had to not buy any other bikes for the next ten years and keep these bikes the way they are (except for replacing what wears out) it wouldn't bother me much.
