I personally would not bother with these lenses. Buy a bellows and some high quality 6 element enlarging lenses ( Rodagons, Componons, etc) and you will be jammin'. Beauty part is these enlarging lenses are dirt cheap used on ebay now due to the many people abandoning conventional darkrooms......
FWIW, I am using 80mm, 105mm, and 135mm enlarging lenses on a screwmount autobellows ( manual mode ) with great sucess lately. I got all of these lenses for less than $80 each on ebay in mint condition. Very cost effective approach....
$80. plus the cost of a bellows. A good achromatic close-up lens on eBay goes from $5 to $15. It does not take place in your bag, or your pocket! Depends on what want. I don't think Rebekah (from original query, see "Cheap macros") would like to go the bellows plus enlarging lens way.
