Went to Lowe's this weekend. They had both Huscavana and Troy Built and trimmers and blowers. Troy Built had two model trimmers that are 4 cycle and don't need oil mixed with the gas. Price on these two units are around between $175-195. Price on the Huscavana 2-cycle units $390. Any opinions on the Troy Built 4 cycles units? Any opinions on the Huscavana units? Thanks.
