Yep, $145 for OS and $145 for Hardware (Core). But most people buy vouchers for these tests, I took both of them for $170 or 180, can't remember.
While A+ doesn't hold much weight, it really shouldn't since its an entry-level cert. Most companies look for three common certs in my expirence; A+, MCSE, and CCNA. Remember that most HR folks might not know what every cert is and what it stands for.
One of the huge pluses of A+ is that it never expires compared to CCNA every 3 years and MS certs whenever they retire them. So as long as you understand that what the A+ is (very entry level) it is a worthwhile cert.
