I LOVE Neutrogena Ultra Sheer Dry-Touch Sunblock. Moisterising but not greasy, nice mild scent, and MOST importantly is a sunblock which is essential in a day moisteriser. About $9-$10 for 3 ounces.
You didn't say whether you wanted an overall skin lotion or a facial skin lotion. There are lots of overall lotions which I haven't found to be greasy…Suave, Intensive Care, etc. all have a range of inexpensive lotions that work well for me. EO (essential oils) is another good line with a range of lovely aromas that you can usually find at Whole Foods but it is pricier than drug store choices.
