$1000 guitar, $150 mic isn't the best combination imho if this is anything other than a demo, but under $200 you can get a couple of Audio Technica mics that are quite decent.
AT2020 you can get for $100 at the moment.
Or the AT 2035 for about $150.
Can you stretch to $200? You can currenty get an AT4051a for $195. They are usually $500.

Don't get too fixated on SDC's- an LDC will do the job just fine.
The last lot of acoustic guitars I recorded were done with a U47, albeit a much more expensive LDC.
