Opti...Again!

Opti...Again! I am replacing the opti on my car again because it keeps losing the high frequency signal. So, was thinking of going ahead with a cam while i'm there. Would need to be able to keep stock valve springs and stuff for a while. Any suggestions? Thinking hot cam kit, it's almost 600 but has everything in it.

You cannot simply throw in the hotcam on stock valvesprings - not a good idea at all!
The hotcam kit does supply everything so there's no guesswork. Keep in mind that when you remove the optispark you're only 1/3rd of the way to the cam. You will still need to pull the intake manifold, timing cover and chain.

I've never seen anyone advise using the stock springs with any cam. How expensive are decent springs?

Didn't really think there would be a bigger cam that I could use with stock springs but you never know unless you ask. I know it's only part way there, but i'm also resealing the intake while i'm putting it on so I wouldn't lack anything more than time. Can you use the Hotcam kit without reprogramming it. If I did put a cam in it, I would have to wait a few weeks to tune it.

If you have an air compressor, you can swap the valve springs with the heads on the car by threading a fitting into the spark plug holes. The stock springs are barely good enough for the stock cam.

There won't be a much more opportune time to swap in a cam, so I would do whatever it takes to come up with the money to get it done.
There is nothing wrong with driving the car unturned for a couple of weeks until you have a chance to tune it.
As for the spring swap...just bring the piston to TDC and replace the four springs at a time. It will be impossible to drop a valve.
