If it's a daily driver, I wouldn't worry about the draw. Mine would sit for 3 weeks, I'd take it around town one day then park it for another few weeks. That caused a problem. The immobilizer is how you bypass your transponder. The transponder is what makes it impossible to start your car without the coded key. You can find ones that don't require an extra key, or you can use a universal bypass module like a 556U that will require a spare key. As far as difficulty goes, the 561 is relatively easy. The viper is far more involved due to the fact that it has an alarm. But for as cheap as the 561 is, you should be able to buy the bypass and have it installed for around your $200 budget.
