So... I was talking to the people at my work and they requested Sirius radio to listen to while they work... and FM has WAY too many commercials. I sort of thought about it for my car anyway, and since I am first in and last out at work, I thought it would be cool if I got one I could use in the car and bring in to the office to let them listen during the day. Then I went on Sirius' website and saw a huge range of prices - $20 for some INV unit and $350 or so for the Stiletto 200. Wow. First I was gonna get the stiletto because I can bring it from car to work no problem - and I could use it when I bike and at home. But in reviews it gets crap reception - so I would need 2 home kits (one for home and one for work) and a car kit. Now we're talking more like $500+. ouch. Honestly I don't really care about using it while I bike - probably get crap reception and you have to use their headphones anyway since they are the antenna... well I break headphones like crazy when biking so I doubt that would work. So if I dont care about mobile use and instead just want car and home, I could get any of the units right? So at the store today I look at the Inv2 - its like $30 WITH the car kit (thats a lot better than $350!). Then for $50 I get the home kit. That should work. But there are about 10 different radios. Honestly, what is the difference between the various ones (other than the stiletto, I get that it's portable). If I got the Inv2 with the car kit, couldnt I just use the car kit to wire it up at my office? We have a stereo out in the shop and I could use the FM transmitter to make Sirius come on some existing FM channel... and it comes with the antenna (but would the car-kit antenna work indoors?). I have a car-voltage power supply so thats a non-issue. Or I can get the Stiletto and buy 2 home kits and a car kit- but thats $$. The plus side is it records songs and sat programs for later replay - but not sure I'd use that. It CAN get signal wirelessly and we have wireless at work - but only DSL so I dont want to use up all bandwidth.... and if I was using wireless anyway I dont need a radio at all since you can listen to Sirius online, so I could plug the computer out back's sound card into the line-IN on the boom-box and listen that way, no? or is there a reason to get one of the other car models higher-end than the Inv2? They ranged from $39 to $199 or so If I get a car kit for my car, does the antenna need to go outside the car? I ain't cutting a hole for an antenna so if it does that option is out. if I can stick it inside on the glass then I'd do it I think. I am so confused... I am debating whether to just get the cheapest car model with a car kit and use that at work (provided it will get reception indoors - will it?). plus side is its cheap and doesnt use our internet bandwidth. Or just listen online and plug the computer into the boom box - problem with that is you need to interact with the player every 90 minutes or it shuts off - kind of a pain in the butt. What to do? what seems the best solution or am I missing something or misunderstanding how it all works?
