I'm kind of liking that US Plastics web site. They even have a 2 quart tank with
a 1/4" nipple already in the bottom. I like this one the best I think:

At first I was thinking it would be cool to have a sensor but if I can see through
it, that works for me, especially at these prices.

I just need to see if the dimensions fit my space.

I just have premix in the car and add it to fuel after filling up, at least you know the ratio is right and no chance of it stuffing up

Two issues with adding it to the tank; the inconvienence of doing so and the oil
to fuel mixture is constant (always worst case). Incorporating the existing MOP
to meter the oil will ensure that the ratio is always correct based on RPM and
it will make the 2 cycle oil go a lot further.
