You can have your own tropical island half-sim in beautiful Otherland Archipalego.
This is a high area sim so you only get 937 prims, but you do get a half sim to put them on. Note the sim is in Otherland which is a large group of private sims and has got a fairly explicit covenant - ie. Mainly residential only and no ban lines
You would first have to buy the right to lease from me and I would transfer the rights to lease the sim to you and you would then have to pay Otherland group the monthly maintenance fee which currently stands at USD$55 for non-european residents or Euro 55 for european residents. For more information see http://www.otherland-group.com ( but do not buy there until I have discussed and made arrangements with the Otherland owners )
If you are interested in taking a look come and check it out - do a search for "Kurendhoo" in the map view when you are in world.
