I used a friends cheapo HF once while hunting. Obnoxiously loud and it made me nervous powering my expensive compressor fridge. The next year my friend had a new little Honda....I would just bite the bullet and go that route.
Harbor Freight has been selling one for years. I have not found one person who has anything good to say about them. If you do buy one, get the extended warranty, you will need it.
Also replace the Chinese spark plug with a Denso or NGK. It will last 10 time longer
