Another Newbie to the Amiga experience

[masteroku]

Hello, name is Daniel. Glad that I had found this place, cause I just bought an Amiga 2000. I am interested in the amiga computer cause since I started using computers(since the 5th grade), I thought only two machines were on the market, PC and Mac, until beginning of this year have i found out that there was third machine that competed with the two others. Since then, my interest for the amiga has grown. I bought my A2000 barely a week ago, so I am almost completely new to the Amiga system. I had experimented with AROS(Amiga Research OS), so I know a good deal of Amiga OS.

I got a few questions that I love to have answers for...

My A2000 does not have a hard drive, I want one, so far i found these two item on ebay for sale, they are two SCSI controllers, one 2091 other 2090.  
-Will these enable me two install any SCSI hard drive?
-Which controller would be best?
-And will I need any software to install them or is it a "plug and play" setting?

Thank you so much in advance, and I hope to get to learn more of the Amiga computer system.

Awsome, glad you all accepted me as part of the club. I will definitely buy a SCSI controller soon hopefully, and enjoy my amiga even more. I also hope to one day to buy the new AmigaOS 4.1, just need to get a machine that will run it(for instance the sam motheboards).

Where Amiga systems sold all over the US, or where they sold mostly in the nothern regions(nothern states)?I live in Texas so,  I want to go to the flee markets or salvation armies or goodwill, to find Amiga parts or computers. Where will be the best bet to find Amiga stuff?

Yeah, I know ebay is the best place to look for amiga stuff. I also just notice that there is a marketplace forum in this website. Gonna check those out. Have any of you tried the AmigaOS 4.0 or AROS?  AROS is prettty awsome(thats what got me into amiga), hopefully the developer team can get out a very stable AROS version soon.

Meh...Welcome to the insanasilum that is the org...You'll never leave...

Yep, never gonna leave  the org, thats cool. I feel like that guy from the California Hotel song...

This place rocks man, I'm getting all kinds amiga stuff offers man, crazy.  I wish i could try the OS4.1, but got no machines that can run that. I was only able to try AROS which I believe is like the OS4. I tried it live on my PC, works well, still had a lot of bugs, even had it installed as my third os(have linux, windows and AROS).

Is the AmigaShell(or command line) a lot like MS-DOS? does it have the same commands as DOS? My 1st pc only had MS-DOS(later got Win 3.1), so I had to learn the command line to access files and of course me favorite, games. I have my A2000 but I have yet to use it cause i am still waiting for the workbench 1.3 disks to arrive by mail(seller forgot to add them).

I live in Houston,
What do you guys think of the revival of the Amiga computer?
Is there a chance for the Amiga to be like it was back in the good ol' days?
