CNP gave you a bunch of real good advice there.
It is just like any other hobbies...one has to start somewhere.
Many will start with a 1X30/42" system. Which is OK. But you will soon realize a 2X72 system is the way to go.
I do realize a budget will dictate everything.
But for steel/handle supplies/hardware, I concur with CNP with the sites he gave you, as I also use them quite often.
Yes, you can check the big box stores in the US...but the shipping/duty/customs will kill you!
You can PM me anytime. No expert by any mean, but I will try and steer you in the right direction, and so will CNP!...
