I use erentpayment.com and haven't had any problems and really like the ease and convenience. They charge $3.00 to process the rent payments via ACH (takes 3 business days to clear) which can be paid for by you, your tenant, or split between the two of you. Lot of options to send reminders, accept/deny partial payments, process/refund security deposit, etc. I haven't used Landlord Station, but 10 for $10/month seems very reasonable.
