I agree with Deon,seeing as I'm a huge fan of large Terrestrial species aswell.

I would opt that for New-World,you could get your'self one of these :
Acanthoscurria brocklehursti Very similar in pattern and colour to the Acanthoscurria geniculata.
Acanthoscurria chacoana Very nice in colouration,better than the Lasiodora parahybana.
Acanthoscurria geniculata They don't know when to stop feeding,always cool to watch them hunt for prey.
Acanthoscurria juruenicola I love the orange on these species.
Lasiodora difficilis
Lasiodora klugi Really big and bulky in size.
Lasiodora parahybana Grow really big as well.
Pamphobeteus fortis If you can find any.
Pamphobeteus platyomma If you can find any as well.
Phormictopus atrichomatus They can be quite defensive like Old-World Species.
Phormictopus cancerides


And for Old-World I would suggest :
Monocentropus balfouri Very Stunning Old-World Species
Pelinobius muticus Probably one of the best Old-World Species for any collection in my opinion.
Hysterocrates gigas

Thanks for this thread, a lot of very useful info and advice being shared.
Personally, my next is going to be a L.violacepes and a H.maculata.
And maybe an A.versi.....

All three are nice, I just need the L.violaceopes.

Thank you so much for all the suggestions so far guys, I am going to take each one into consideration and do some reading up on them all.

By the way Deon I envy you for the fact that you have a T I'd really would love to have but due to them being so scares and pricey it will take a few years before I own one indeed, I am referring to your G. Pulchra.

Hi Vix, my G.pulchra turned out to be male when we checked it's last molt. It's still a juvie, now about 8 cm, but my friend has a slightly older female, so hang in there, I'll keep one aside for you as soon as they're big enough to breed.

Hello Deon

How is the G.Pulchra's temperament ? Also, if you do breed them keep me in mind as well. It is a stunning T in my opinion, but not seen up for grabs a lot.
