I am trying to convert 100% to metric, at least within my garage, and I need a metric tape measure.  I have a Festool folding rule, which I like very much, but there are times when a tape measure is more convenient.  I have looked at the Festool tape measure, but I am thinking I need something a little more rugged, and I prefer something in the 16 foot,  oops, 5 meter range.  I found this and was wondering if anyone has any experience with it:  http://www.starrett.com/saws/product-detail/Jobsite-and-Shop-Tools/Hand-Tools/Tape-Rulers/Measuring-Tapes/KTXP106-5M-N

Look for the following brands:
Lufkin, Stanley, Sola, Fisco, Stabila and Fastcap.
You'll probably find a suited model among these brands.
BTW. Fisco, and Sola share the same models.

I personally advice the Hultafors Talmeter 6m model, but maybe it's NAINA.
It has some really nice features, from which the steel pen under the tape is the nicest.
You don't have to use a pencil any more. Just lock the tape measure and press or scratch the pen to the object underneath.
Sorry for the large picture, but you can clearly see the steel pointed pen.

Fastcap also has a flat version which I really like.  Still, there are times where the rigidity of a C shaped tape is desired.  So get both!    I only got this one recently, so no long term feedback.  No experience with the Starrett, either.  

There are many that offer both imperial and metric markings on the same tape.  Personally, I don't like them.  I'd rather have two different tape measures, however I'm at home when I'm using them, so it's easy enough to reach for the one I need at any given moment.  If that wasn't the case, I'd want both in one.  Interestingly enough, 2 weeks ago I turned my [imperial] Kobalt tape upside down...whoah!!!...metric markings!!  Somehow, in the 2+ years I've had that tape, I never looked on the backside!  Doh!

I have the Fastcap and the Stanley metric/imperial, but I always seem to reach for the Festool tape measure. I like the weight...it's easy to keep in my pocket. The scale is easy to read.

True Value sells a US/metric tape.   I forget the brand name,  but quality is fine and you can get it today.

It sounds like you've sorted out a tape...
maybe worth a mention...
In the workshop I generally use flat metric rulers. On site I have 3 identical brand, model, batch 8m tape measures. One inside, one outside where cutting and one in the ute. I don't carry tools- I don't like it. By having the same tapes I get consistent measures/cuts.
I don't ever mix and match rulers and tapes because they 'can' differ- very slightly, but enough.
The point: whatever you use to start the project- use the same to finish the project. Saves frustration.

Lufkin over Stanley every time.  

Nearly finished an owner build. In four years, went through two Stanley tapes in two years, then purchased a
Lufkin which I still use.

Also do not purchase a imperial/metric tape, you will only confuse yourself!
