Offers a database for you to sort based upon your parameters. In general, here are a few tips for selecting an ETF:
Expense Ratio - the lower the better. Basically, the expense ratio (Expense Ratio/12 months/days in the month) reduces the ETF on a daily basis to assure that they make their bottom line. SPY, VOO, QQQ are popular examples with low expense ratios that reflect the market. In general, the lower the ratio the better.
Volume - volume traded impacts liquidity which reduces slippage (difference between the bid vs ask)
History of performance; not just the current ETF, but all ETFs they have opened
Holdings - what are they holding, do they cover the sector interest or the entire market, are they focused on large, mid, small caps?
Dividend yields and total returns
