First of all, it doesn't matter. I have a $20 digital timer that works just as well as my dial timer. It REALLY doesn't matter at all. Just go to a hardware store and get the cheapest one.
Secondly, you are coming across rather rudely. I'm not sure if its intentional. Please don't take this in the wrong way, but everyone that has posted here has tried to help, and those that gave up on helping probably did so because of the way you are commanding them to give you the answer you want to hear. As I said, I'm not trying to make you feel bad about it, but it's a good thing to treat everyone nicely, especially the people who have been helping your for eight pages.
To summarize, get a 20-30g tall aquarium from petco. Get a glass hood for the size aquarium you choose. You can shop around awhile for a light you like. Make sure it's 4500-6500k, which will lOok yellow when on. The higher wattage the better, but keep the kind of light in mind. T5 provides a better spectrum than power compact, but if it's a 20w T5 versus a 100w power compact or fluorescent, go for the higher wattage. Get a humidity gauge and a thermometer while at petco, which should be around $10 total.
I wrapped my terrarium in foil to reflect the light so that the plants get as much as possible. Don't forget to ask questions as you go. Donresearch on everything before you buy it. With a terrarium, you'll loose less plants and they will grow better.
