Your wheel (rim) could be damaged so you should have a tire shop take a look at it. You can probably get a tire for like $30+, and maybe $10-$15 to balance it. Try a used tire cause most tire places would suggest changing tires in pairs.
There are currently a number of HDHomeRun models on the market: a single-tuner ATSC/clear QAM model, a dual-tuner ATSC/clear QAM model, a dual-tuner commercial (TECH) ATSC/clear QAM model, a dual-tuner DVB-T/unencrypted DVB-C model, and a three tuner CableCard/clear QAM model.
This is an odd looking little instrument, but it shows typical Seagull quality, despite it's less than showy finish. It is light, tunes easily, and has a fuller sound than other similar strum stick type dulcimers. A little tricky to hold while playing, but not as bad as some travel guitars I've played. A strap helps a good bit. For this kind of dulcimer guitar, it seems to be the value leader in sound. The short scale is a little limiting, but it still has many uses and has to be a best buy.
