Yes: ChecksForLess.com. This is for a Pre-Printed check (not a blank MICR check). The specific check stock that works best with ResMan is ordered by a fax/email/mail in form (http://www.checksforless.com/pdfdocs/orderform.pdf). Pricing for these types of checks can be found here http://www.checksforless.com/lasercheckpricing.aspx. The checks are the same price as the Laser Voucher Check LV1.
When ordering please order the check stock format 9058. That format allows you to specify company, bank, check number, and MICR line but allows the software to print everything else.
