I will argue that OME should be at the top of your list...
While not on the top of my list, it hasn't been ruled out! I like 4runner by the way, I had an 89 that I used and abused all across Arizona, California and a couple trips south of the border. I'd like to get back into one someday...
The downside is I don't think OME has anything specifically for a Tundra, which means guesstimating which Tacoma springs would best suit your needs....not that you couldn't or shouldn't go with OME, just going to take a little more thought and calculation to get it right.
Right now I'm running a used set of rebuilt Donahoes that seem to be a great all around setup......new ones(ICONS) were a bit too pricey for my blood though.

Slee Off road offers a pieced together kit:
"2 x OME885 Front Coil Springs, 2 x 90004 Front Struts, 2 X N182 Shocks, 2 X Rear Add a Leaf Springs"
For a little under 700, I've heard mixed reviews of ride quality with the 885's on tundras though... I'd be one happy fellow if I came across a good deal on a set of ICONS, but I have a trip coming up in May that I need the truck ready for, so time is something I have to keep in mind.
I happen to drive said DC Tundra and while I have no experience with OME or Toytecs stuff, I can share my experiences about the Bilstiens.
It's been two years and 45,000 miles and the 5100s are still going strong just as good as the day Jim and I mounted them up. Installation was easy-peasy, the hardest part was just finding someone open on a Saturday afternoon in Virginia to compress the coils form the stock units and swap them onto the new Bilstiens. The ride is better than stock and the Bilstiens look like new. No leaks, sagging or anythin'. My truck see's heavier use daily as a work/construction rig than the majority of vehicles on the forum and sees light to medium duty wheeling when it's time to play. The only major change I made to the truck was to swap out the factory leaf springs with AALs for a custom set of Deavers as with all the towing I do the factory units just weren't up to the demands I was placing on the truck. They are a great option and are by far a great deal for the price.
That sounds like what I need! something that functions well in wide range of tasks. My trucks a bit older (02) and over 170k miles, do you think my springs have enough life in them to be reused? this was my main thinking in looking at the Toytec (Eibach) coils. I do like the price of the OME setup, I'm just not sure it's the way I want to go...
Thanks for the input guys!
P.S. I'll post pics shortly
