Best C compiler for Amiga?

Note sure if this is the right site/forum, but thought I'd get some opinion...

What is the best C compiler for Amiga?

I'm not sure if any of them make it easier to design GUI interfaces, but that would be a plus.  My app would only need simple GUI but still would need it.

Free is preferable, but I'm also not going to settle for free when the pay version is so much better..

Serial I/O is a key thing, so if one has notably better serial functions that would be helpful to know.

Thanks!

Oh I forgot to mention that the target platform is preferably ALL Amiga's, but if it makes a difference I'd rather it work on classics.  (1.3-3.1)  If the program will run in a WB compatibility mode on 4.x then that's fine with me.  I will probably never have anything other then classic hardware...

Don't care too much about the debugging...

The compiler needs to support Stock/Original Amiga 500 targets (68000/1.x/512k+ RAM)...   Since all I have is the above mentioned target right now, it will either need to be a Windows (such as the first one mentioned here) compiler, or something else...

edit: NovaCoder - missed your reply when I wrote this -..  Will CubicIDE or StormC (sounds familiar) run on A500?  I'm building a 2meg/IDE upgrade to help there..

Thanks,

What about a simple editor and a command line compiler?

Will anything like that run on an A500?

Thanks

What was the standard compiler for A2000 back in the day?  Certainly it had a compiler available for purchase?

I don't care about MUI, RTG, etc.  I prefer original A500/A2000 (and A3000) computers ... If I want to keep upgrading an Amiga to be modern I might as well use a PC (which I have several).

Thanks for all your comments!  

I want to try a lower end compiler first..  Coding on the A500 might be counterproductive but I want to try it first.  If I feel the need to use WinUAE or Windows I'll look at some better options.

Does anyone know where I can get Lattice or SAS/C cheap? Or is it freeware now?

Thanks,
