Extensions Plus?

Now that Brigid and Billy have experienced the Tiffany Twist strand by strand application, they are already bugging me for their next DIY "test" install. 

 

I am in the first stages of putting together the next install for when Brigid comes back from Australia the first week of September.  Brigid has been reading the boards here at HB, at BHM and 101 to get some ideas of what she might like to try as various installs since we are going to test several.  We are going to do a weft install next.  

 

I have also been checking out good places to buy the very best hair and a celebrity hairdresser friend of mine today told me that down the road I should definitely check out Extensions Plus for really top of the line hair.  I checked the place out and read Diva's & other's notes about calling them to order but honestly the options seem daunting.  I know they are really expensive so I don't want to make a mistake my first time with them. 

 

Any suggestions for dealing with EP would be appreciated since when I try to figure all this out my eyes start to glaze over.  :-)
