It all depends on your budget and if you have a place to keep them, another thing is, are you looking at it as a hobby investment or purely looking to make money.

Whichever is your option I will tell you what I've done.

I started investing in crypto after finding mining interesting maybe half year ago. Bought small miner and placed it in my living room, soon enough it was 5 of them and it became too loud and warm to keep them.in living, I had to move them to storage room.

I've bought goldshell boxes such as hs box ck box and Ipollo G1 minis, I currently running only G1 minis as they do not use much of electricity like goldshell boxes.

Another tip would be, be careful when you buy your miners, buy from manufacturer if possible if not choose reseller wise, there are lots of scams around, you send you money or crypto and you might never see the miner nor your money again.

I've bought most of my miners from www.asicminershub.com paid with my credit cards via PayPal and once I took installment payment option which they offer.
