There is nothing wrong with a FLIR B50. It is a great camera for building diagnostics. You just have to remember that limitation. You will be able to also handle residential electrical.
I am not a big fan of starting in the middle when it comes to cameras. I think in the long run you do yourself a lot of justice by starting off with a little less camera and spending the extra money on training. Then in the future buy one of the big boys once you understand the industry. I know others will argue that fact here, but those “others” have a few years experience under their belt in the industry and most of them started with lower end cameras. What I mean by lower end is 160x120 minimum with no higher than 100mk thermal sensitivity (now a days it is actually hard to buy one this high). Your B50 is 140x140, which is basically the same as 160x120.
IR is a very profitable industry, providing you do not allocate yourself to residential only. Most that “struggle” in the industry have a build it and they will come mentality. That type of business model rarely works, unless you have a completely niche product or service that is a big break through. IE - Google in 1998.
If you do not mind doing a lot of client (potential or current) education, then even the highest levels of infrared training costs will pay off in a short amount of time. We do jobs now a days that will buy you just about any camera you want…on just one job.
