The differences in using a kick wheel opposed to an electric one can only be found out be truly trying each one first. The shops in which you take your lessons will most likely have one or more of each type of wheel. Another plus in starting out through the use of lessons is that you will probably waste quite a bit in materials as you first start to figure out how to truly make the clay mold correctly and shape into what you want it to be. The final note about started out in this hobby by taking some lessons is that most shops also have kilns. When you do decide to take the jump and buy a wheel for your home you may find that you have enough cash for the wheel but probably not for a kiln.
Most potters starting out can rent kiln time at some of the more friendly pottery places.
Finding a used pottery wheel is probably the most cost effective way of starting to get some equipment. However, when they are advertised, they disappear very fast. Try to by the first caller when you see an ad posted and the first one to visit. The wheels won't last. If you can afford a new wheel, please go that route and there are tons of avenues both on line and through supply stores where you can find wheels of all types and models.
