Problem is, it works fine as is -- what I'm looking for is preventative maintenance and I'm not sure I would recognize it if something were amiss and on the verge of failure. I'd much rather give this to someone who knows wtf they're doing even if I have to pay them for their experience and knowledge. I know -- pay someone for their experience and knowledge -- who does that? Well, I kind of depend on people paying me for mine, so once in a while I don't mind paying other people for theirs, especially if it's something I know diddly about.
