Computer first, then add power-meter?
Or is there a Power Meter that comes with a computer read-out that will also tell me my speed, that would be more economical?
How much should I expect to spend, if I want to spend the least possible?
If you're definite about wanting power, and have $650+ now, go with a GPS computer at $150+ (e.g. Garmin 500) and a power meter at $500+. Or cheaper second-hand.
You can get it all but power and GPS for well under $100 with a non-GPS bike computer.
And if you have a smartphone, you've already got the GPS there, and you can mount the phone on the handlebars or use the Wahoo RFLKT ($130 or less) to display key info.
