I just finished using two boring bars from one of those $20 9 piece sets from Ebay.
Some one asked about them so here is the report.
The look and feel compaired to a Sandvik is terrible but I am a new kid and money is important. Making models, my time is cheep so I tried them in cast iron. I mounted them in a sq head Criterion boring head (another Ebay find) Went nice and slow. Never more then .02 at a time, and obtained a very nice finish with no problems
Summery, if you aren't making your living with them, they are OK.
