I got my Blackhawk 45 convertible second hand almost 30 years ago and have had no problems, even after firing thousands of rounds. The Bud's price you mentioned sounds good but don't forget to add in the shipping and FFL transfer fee. That could bring the cost up to what you would pay in a local gun store. Might be worth checking out.
Like so many others, I suggest you look into reloading eventually, especially for the 45 Colt cartridge. The cost is probably less than you think, especially if you deal with Midwayusa or Cabelas. A basic Lee Single stage press is less than 30 bucks. The other basic tools: a reloading manual (the one by Richard Lee is comprehensive, instructional and inexpensive), Lee powder scoop set, safety scale, powder funnel, hand primer with shell holder, Lee carbide dies, and a tray to hold the cases upright, don't cost much (I would guess under 100 dollars) and are one time purchases. With the possible exception of the hand primer tool, they can all last a lifetime. If you decide to reload for 45acp as well, the only other things needed are the appropriate carbide dies and a shell holder for the hand primer.
If you decide to try reloading, or just get curious about it, chances are your local library has books and manuals available. Also, the reloading forum here on the TheHighRoad has a wealth of information and knowledgeable people.
Hope this helps.
