Llanowar Sentinel and "Chaining"

[Tempe]

If I play a [card]Llanowar Sentinel[/card] and use its ability to find another, can I then use that Sentinel's ability to find _another_ Sentinel until I have all 4 in play? Can I use the first Sentinel's ability more than once? Thanks in advance.

When the Sentinel comes into play, its triggered ability goes on the stack.

When the trigger resolves, you can pay G1 to search for another and put it into play.  You can only pay G1 and search for one.

When the other comes into play, its ability will trigger and you can repeat the process.
