I too use ING. Besides the high interest rate (compared to B&M), they pay you the interest MONTHLY. For a payroll deduction, all you have to do is schedule automatic withdraws from your linked account...that's all I do. Plus, the usually have nice prize drawings every year for those that deposit at least $100 per month.
If you want a referral, send me a PM with your name and email address. Last I checked, you'll get a free $25 deposit with the referral and I'll get $10.
