Yamaha C40 seems to get praise- I don't have one.

I like Cordobas because they have a truss rod, and I think that increases the length of viability, because necks tend to bend over time- 12-15 years and you have to get a new guitar otherwise.

The Iberia series is best - there are a lot of C5s used on the market these days-warm sounding cedar tops, mahogany back and sides, usually good quality
if you go through Guitar Center- they have a good refund policy that keeps you from getting burned

I've bought blems on ebay with "defects" you can't even see that are new condition otherwise at substantial savings
a new C5 I think retails for $300- so maybe you could go that high or find one used.

Epiphone puts out a cedar top classical guitar for just over $100- but I haven't seen one personally
