- It's pretty cheap. The SWS models can get up there (and I've since picked one up) but you can get a decent Seagull for under $500, and it won't break the bank.
- Seagulls generally have wider nut widths, which gives a little more breathing room between the strings, and is great for finger style and the 'fat finger' feeling new guitarists have.
- They sound AMAZING. For my last guitar, I was dead set on buying a Taylor 514CE, but playing it side by side next to Martins and solid body Seagulls, I ended up getting another Seagull. Obviously, this is as subjective as the ongoing 'Martin vs Taylor' holy war, but I took a neutral party to blind listen to me playing so as to mitigate the confirmation bias, and they picked the Seagull too (though obviously, I was more keen on the Seagull architecture, which I'm sure did bias things).
All that aside, I don't think I got really serious about learning guitar until I ultimately picked myself up a Les Paul (per your advice) to effectively "get more skin in the game", as well as to know that whatever mistakes I made were mine, and couldn't be blamed on the guitar.
Also, in addition to justinguitar.com, I would add Marty Schwartz, who has a Youtube channel at http://www.youtube.com/user/guitarjamzdotcom.
He teaches a lot of beginner level, few-chord songs that people know and recognize, and even though I know that it's a Youtube video, and not interactive, the videos are recorded with a great deal of patience.
