The only cups I know of that don't need specialized tools are bra cups and coffee cups. Whatever BB you buy will need a specific tool, and as others said, it's just the cost of doing business.

Another alternative, if you live near a bicycle co-op is to join, and use their workspace and tools. Some people and bike clubs also have informal tool share co-ops where people pool their cash to buy some of the relatively costly, but not used every day tools such as a derailleur alignment gauge.
