If someone mails you a PAR meter to use, it will cost you about $10 minimum for postage, then an equal amount to return it, so you will be out over $20 just for postage and handling. Assume whoever loans it wants to earn a little for his trouble, say another $20. That means just borrowing is likely to cost you around $40. If you buy a Mastech or other #LX1010B lux meter it will cost you about $21, minimum, with shipping included. Google that part number and look at the "other deals" on the Amazon site.
