I have noticed a SB 38 edger for sale locally, and would like to know it they are worth buying? It looks in good original condition and the seller said the engine is good and it works fine, but they are asking $150. I think it is a bit of the expensive side.

What things should be checked before making an offer? Are there common faults or items that give trouble on the 38? Also are the SB 38 edger reliable and easy to use?

Or has this type of edger been made redundant by the modern line trimmers, which can be used for more tasks than just edging.
