I want to buy bamboo blinds!!

I am helping my mom in picking out and buying Bamboo blinds and was hoping for some advice on different manufacturers. First we looked at Levelor and Bali at the local home store. For our windows these are going to run from $150 to $200 each. The kid at Lowes said he has the least problems with Levelor, but Bali customer service is easier to deal with. I would prefer never to have to talk to either and want them to just work! :-)
Meanwhile online my mom found a few places that seem to offer the same type of product, in custom sizes, for far less. From $50 to $80 each. These companies are Best Blinds (bestblinds.com), Island Blinds (islandblinds.com) and Top Blinds (topblinds.com). abrasivesabrasivesabrasive wheelabrasive wheel
Does anyone have experience with any of these companies or Bamboo blinds in general? I did searches on each with "opinion" and/or "review" and didn't find anything. I am wondering surgelightningif there is a huge difference in quality in the lower priced online suppliers. Is it too good to be true, do you get what you paid for, or are the big names making us pay for all their marketing? Thanks in advanced anyone passing by and leave a reply. baseball helmethockey helmetpipe fittings mouldMagic cubeMagic cube
