1 Did she ask you for help in finding a rig, if not keep your nose out of it, for the first time something goes wrong it will be your fault.
2 If she did ask for help, keep it as limited as possible, e-mail her links to ones you find on Craigslist or other resources. But only ones in her price range, and of the type she is looking for, and make it clear you are not endorsing any just showing her what is available. If she finds one she likes, stay neutral, and have her take it to a trusted shop to be looked over.
But as stated above keep your input as little as possible, because if you don't, remember all problems will be your fault.
