Most of the seller's feedback is positive, considering the amount of stuff he/she has sold. Three negatives and two neutrals in 12 months, which isn't too bad. If the responses are to be believed, it appears that refunds were given. It looks like this seller has no trouble getting bidders going with the low starting bids. He/she may have kind of a regular following.
I too am always leery of bad spelling, especially when there doesn't seem to be a genuine language barrier. It just seems sloppy and unconcerned, when a seller should be doing their best to make an impression, especially with high-dollar items.
