Firstly, welcome to this friendly forum Miguel. 
Secondly, congratulations on your efforts in building the scope.
Back in 1978, I built the Practical Wireless 'Purbeck' scope, but at least here in the UK, we can easily get parts quite cheaply at a price we can afford. I made the PCBs myself - the power supply PCBs are easy to make by using sticky plastic (we call it 'Fablon' in the UK) stuck onto the PCB and cut out tot shap with a small craft knife.
You might find the Purbeck article of interest and might pick up a few ideas from the circuitry for your own scope. It was in six parts, with a follow up article of corrections. All seven parts were posted on the UK VRF back in Feb 20111 by Keith (‘Keiths’ TVs’) who pu5t in a lot of effort to scan and upload all seven parts of the article. Keith is – like you - a recent member of this forum too. You’ll find the full article and the follow up article of corrections here:

If you look in the homebrew section of this forum, you'll find several projects which forum members have built.
Best of luck with your scope project Miguel.
Enjoy the forum!
