But some of them are listed as scam, and then I decided to ask you guys
I have 1450$ that I can use.
For $1450, you will be hard pressed to find an affordable BTC miner. There are indeed a lot of scams out there, so be careful. If you are uncertain, check here to see if there are listed as scam anywhere or just ask. As mentioned earlier, the ASIC manufacturers that have had a successful delivery are few. BFL is notorious around here for delaying their product about a year. Therefore, you likely won't find anyone actually advocating for them on their behalf in these forums. Their currently available offering of miners are and will be further outdated as newer, more efficient tech is already on the network.
If $1450 is your budget, it is likely that your most financially sound advice would be to purchase BTC and hold as previously mentioned.
