Current Mortgage Refinance Options

I am looking at mortgage refinance options now (with rates being so low). I am looking at 20 year fixed rate loans with cash out (with over 20% down). The 20 year term will reduce my loan term a bit, and the final monthly cost should actually be not much higher than my current payment (with taking some cash out), I think. Do any readers have opinions on these lenders (or others with competitive offers – low rates and low expenses)?

Total Mortgage – 20 year fixed rate 3.875%, total fees and points not provided :-(, apr 4.15%

American United Mortgage – 20 year fixed rate 4% [same as 30 year rate :-(], fees $2,995 (0 points), apr 4.26%

Aim Loan – 20 year fixed rate 3.875%, fees (about $4,100 I think), apr 4.02%

These are some of the best deals I have been able to find. However, companies can play games with fees and hide excessive costs in requirements they don’t consider fees (appraisal costs…). Rates can bounce around for a specific lender, so I think it make sense to watch several (not just pick out he lowest one on whatever date you first look).

Suggestions on how to tell whether specific lenders good faith estimates are accurate and comparable would be especially appreciated.
Edits:
RoundPoint – looks good, low rates, low fees, good reviews on Zillow.
Amerisave – 20 year fixed rate 3.75%, total fees and points $3,418, apr 3.87% (removed as an option – they don’t respond to customer have tons of negative reviews online about problems, poor service, etc.
