Im not familiar with MACS but maybe this suggestion is similar,
There is a product called dynabeads by invitrogen and they reckon they are very efficient in separation,
The only catch being they can separate cells only on the basis that a membrane/cell surface protein can be used to separate cells
Basically if your cell type has a known membrane/cell surface protein that all other cells in a mixed population dont have you can purchase antidodies from the same company (they can even make antibodies for you if there are none available for your particular protein),
They then link this to a primary Ab to a secondary antibody which has a metallic element attached to it which can then be separated using a simple magnet held against the side of your eppendof tube or column while flusing out the remaining cell popultion, so no hi-tech equipment is needed.
I've attached the link to their home page
hope this helps,
i found the company very helpful whern i enquired about the products unfortunately we could not use it due to having no cell specific cell surface protein so try give them an email.
