£150-200 would suggest your in the UK.
Avoid Connemara if he is not into peated whiskey but pretty much everything else should be fine.
You have 2 good options and both have reasonable postal charges. Further anything in your price range will be a nice and decent bottle.
The Whisky Exchange in the UK
Best bottles here would be
Redbreast 15yo
Jameson 18yo
Midleton Very Rare 2010 (The 2011 will not be released till the end of the year)
There is also the Jameson Rarest Vintage 2007 which is £250 and possibly too expensive but an amazing whiskey.
&
The Celtic Whiskey Shop in Dublin
Currently the CWS has a bigger selection of Irish Whiskey.
You could go for a
Jameson Gift box which has 3 x20cl bottle of their reserve bottles with a 12yo, Gold & 18yo. SO 3 for the price of one.
As mentioned earlier there is a
SIngle Cask Midleton which is a fairly exclusive bottle.
Even more exclusive and slightly above you budget is the
A Limited Edition Green Spot and comes in a decent wodden box.
However if you know some one in Dublin they might Pop in to the Jameson Heritage Centre in Bow St and get you a Personalised Jameson 12yo. You could then buy another bottle also maybe like the Redbreast 15yo and you get a Birthday boy who it twice as happy
Just to let you know the Bow Street 12yo is actually a different whiskey to the regular Jameson 12yo.
