I have used a Stihl FS90 (bike handle) for past few years and have no complaints other than hard to use as an edger.
Recently picked up a used Shindaiwa 242 that came with string trimmer head, AH hedge trimmer, and both long and short shafts. It's a complete trimming and hedging package. Really like the balance of the short shaft with the AH hedge trimmer, and the long shaft for trimming high shrubs. Will probably be using the FS90 only with a brushcutter blade now. I'm now a Shindaiwa fan for trimmers.
