If I spend $150 on a cheap used guitar, I can play it for 6 months before my technique justifies something better, if I get into it again.
If i don't, I can prolly sell that $150 guitar for $125 or more. Very little risk, very little capitol tied up, very little chance of my wife *****ing because I'm letting a $1500 guitar gather dust

i may decide I suck and don't enjoy it, who knows?
Plus it will help me determine my style and what kind of music I'm into so I can get a good guitar that compliments that style. I used to play a les paul because I was playing, well led zepplin.
I'm probably more bluesy now, maybe even ...... dare I say it ...... folk.
A nice telecaster might suit my style and likes better now, don't want to buy something really nice and then decide I want something more mellow or more whatever.
I used to love my ovation round back because it projected highs well, but not as much bass. I don't think I'd like that any more.
BTW Todd, I once played a set with the ventures (minus Okie) at NAMM using a guitar custom built for Dick Dale so I do like surf music
(that was my 15 minutes of fame so it's all used up).
Word to the young guys, don't do anything special when you are young. Save that 15 minutes so you have something to look forward to.
