You should go old models, unless you really have money to burn for spiffy new design and not that much difference in power (unless you use those ginormous tips (think quad tips for metcal) or those JBC C470 tips which can deliver 250W with appropriate station).
I'd suggest trolling around ebay, or whatever other resource there is over there for used items searching for something like a Metcal STSS, JBC AD(2700/2910/2950/4200/4300) [AD prefixes each number]. The lowest I've ever seen an STSS + pencil go was 135$, still requires a standby stand. The lowest I've seen an AD2700 go was somewhere around 150, standard kit (psu+iron+stand). I've also seen the 4300 go for 175$, PSU only.
Also, if you really do want an Ersa, I see at least 7 i-Con's on ebay Canada (means restricted to auctioneers who say they'll ship to Canada, typically). I see a 200$ USD BIN which includes the PSU, iron and iron stand, I kind of expect similar in Europe.
used soldering irons are a great way to save bucks if you're already inclined to purchase a new one as tips tend to be the large determination in performance. though I'm not sure about the durability of the fancier digital interface PSUs.
