I don't know your budget but my first choice would be columbo. I've seen their spindles run in cabinet shop CNC machines for years taking abuse from the wood workers.

You don't mention any details, so I'm only guessing as to suitability, but seeing as it's home made I'm guessing budget is limited, so I would highly recommend these:

Absolutely dirt cheap and just works! I would think impossible to beat on value.

On the small side (as mentioned, you haven't specified) there are a couple of options:
Sherline have spindles rated to 10k, see here: http://www.sherlineipd.com/spindles.htm
A cheaper alternative is the Taig headstock which are also suitable to around 7.5 to 10k.
I have one which was intended to be put to use as a cnc spindle(my old thread here: http://www.homemodelenginemachinist.com/f13/taig-er16-headstock-15548/), tho still not used it :hDe:
Both have ER16 collet spindle options.

What do you intend to cut and what sort of accuracy are you looking for(is your machine capable of)?

When I was looking I didn't find anything that was worth the money in the cheap stuff or it was way out of my price range.

If you are not doing heavy milling then a Rotozip will work. I have an adapter that connects the Rotozip to the spindle on a Bridgeport clone CNC. I think the Rotozip runs at 30,000 rpm.

According to me, The High speed milling spindle is one of the best for your home built cnc mill because it works very well with it. It uses three angular contact high speed spindle bearings. And the chosen motor should allow up to 30,000 RPM. I hope this information will help.
